4 Claims.

The invention relates to Wiring cleats, particularly of the strip type having a projecting end of sinuous form so as to be capable of supporting insulated wires that are laced or otherwise bound into a cable as is usually the case with switchgear control wiring or in other similar service involving a multiplicity of wires.

One object is to provide an impdoved embroidered double-hook sinuous strip form of wire cable supporting means that is self-locking with the wires bound together to form the cable.

Another object is to provide a unitary angulated and sinuously ending strip form of cleat that is equally suitable for supporting a few or many wires bound into a cable and having a sinuous or S-shaped double-hook end of the cleat embedded inside the cable when formed of many wires and the other angulated and offset end is seated in each hook of the double hook memof the cleat extending laterally from the cable to facilitate mounting the cleat.

Further objects and advantages of the invention will appear in the following description of the accompanying drawing in which Fig. l is a side view of the improved S-shaped sinuously ending and angulated strip form of wiring cleat shown supporting a cable composed of many wires bound together around the S-shaped double-hook end of the cleat; Fig. 2 is a similar view showing the cleat supporting only a two-wire cable; Fig. 3 is a perspective view of a panel having both the two-wire cable and the multi-wire cable mounted thereon b means of the improved S-shaped double-hook form of cleatand Fig. 4 shows a modified form of the cleat.

As shown in Fig. 1, the improved sinuously ending and angulated strip form of wiring cleat indicated generally by the reference character I0 has the angulated end I I thereof forming an on?- set support and provided with a suitable hole for the mounting screw I2 that removably secures the cleat to the panel I3. The other sinuous end M of the cleat I0 is formed into an S-shaped double hook for oppositely anchoring in the reversed hooks Ma and Mb a pair of adjacent wires I1 and I8 that are bound into a cable by the lacing I9 as indicated in Figs. 1 and 2. Thus when only the two wires I1 and I8 are bound together to form the cable as shown in Fig. 2, the hook Ma, formed at the sinuous end of the wiring cleat seats the wire I1 so as to prevent movement of the cable in all directions except to the right, while the reversed hook Mb formed adjacent the first hook oppositely seats the Wire I8 so as to prevent movement of the cable in all directions except to the left. In this way, a separate wire of the cable ber' I 0 to be oppositely hooked thereby and thus lock the cable on the member. Consequently, the double hooks Ma and Mb cooperate with the wires I! andI 8 to prevent movement of the cable formed thereby in any direction.

When a multiplicity of wires are extended transverse the double-hooked end of the Wiring cleat II] to be laced together into the cable as indicated in Fig. 1, a pair of anchoring wires IT and I8 are each seated in a corresponding one of the hooks Ma, and Mb to be oppositely hooked in exactly the same way as just described in connection with Fig. 2. In addition, the adjacent layer of wires 2| inside the cable are compacted around the anchoring wires I! and I8 so as to engage therewith as Well as with the sides of the S-shaped double-hook end of the cleat It to be supported thereby while the outside layer of wires 22 is in turn compacted around the inter,- mediate layer of wires 2| so as to be firmly supported thereby. Thus all of the wires in the multi-wire cable shown in Fig. 1 are firmly supported by the cleat I0 with the S-shaped doublehook end M thereof embedded inside the cable before the wires are bound together by means of the lacing I9.

As shown in Fig. 3, the two-Wire cable is easily and quickly mounted on the panel I3 by first securing the two spaced-apart cleats I0 thereto by means of the mounting screws I2. Then the wire I! is seated in the hooked end Ma of each cleat It and the wire I8 oppositely seated in the adjacent reversed hook portion Mb of the cleat and the lacing I9 applied to bind the wires together into a cable. Likewise, the multi-wire cable is mounted on the panel R3 in substantially the same way except that the intermediate layer of wires 2|, together with the outer layer 22, are laid or bunched substantially symmetrically around the two anchoring wires I! and I8 before the lacing I9 is applied. Due to the offsetting of the supporting end II of the strip It, ample room is provided between the cable and the panel I3 for applying the lacing I9. Also, the mounting screws I2 are readily accessible in case it is desired to bodily remove the cable from the panel.

In the modified form of cleat shown in Fig. 4,

; a third hook portion Me is provided in the cleat I0 between the double hook portions Ma and Mb within which the wires forming the cable are mounted and the laterally offset end I I that forms the support for the cleat. This third looped or hooked portion I 40 insure uniform spacing of the wire-supporting hooks or loops Ma and Mb particularly when the supporting end ll of the cleat is spot-Welded to a metal panel.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. The combination of a supporting strip hav ing a sinuous S-shaped double-hook end and having the other end thereof angulated to form a support offset to one side of the S-shaped double-hook end of the strip, a plurality of wires extended transverse of the double-hook end of the strip to seat a separate wire in each hook thereof, and means to bind the wires to form a cable having a pair of the wires oppositely hooked by the double-hook end of the strip to lock the cable on the strip.

2. In combination, a plurality of Wires, means to bind the wires to form a cable, and means for supporting the cable comprising a strip having an angulated supporting end offset to one side of the cable and a sinuous end forming an S-shaped double hook extending inside the cable to seat a separate wire in each hook and thereby lock the cable on the strip.

3. In combination, a plurality of wires, means to bind the wires to form a cable, and means for supporting the cable comprising a strip having an angulated end forming a support at one side of the cable and a sinuous end forming a hook extending inside the cable to seat therein one of the wires of the cable and a reverse hook adjacent said first hook for oppositely seating therein'another wire of the cable to lock the cable on the strip.

4. The combination of a wiring cleat comprising a strip having a sinuous S-shaped doublehook end and having the other end thereof angulated to form a support offset to one side of the S-shaped double hook end of the strip and provided with a spacing loop interposed between the offset supporting end and the S-shaped double hook end of the strip, a plurality of wires extended transverse the double hook end of the strip to seat a separate wire in each hook thereof, and means to bind the wires to form a cable having a pair of wires oppositely hooked by the S-shaped doublehooked end of the strip to lock the cable on the member.
